What’s the point of a daylight alarm clock

Are you tired of being torn out of your most beautiful dreams every morning by your loud alarm clock ? Are you still in deep sleep and need a few rounds of the snooze button to get out of bed?

Then this morning ritual is definitely a significant burden for you . You start the day with a lot of stress and you will be torn from your sleep.

The daylight alarm clock promises a gentler approach. It simulates a natural sunrise and wakes you up like the sun would do in nature.

What does a daylight alarm clock do for you and in this way does it really serve its purpose?

The human internal clock is still based on the sun . Even with the arrival of artificial light, this biorhythm is not discarded.

The sleep hormone melatonin is largely responsible for the day-night rhythm . This is formed in the pineal gland and makes you feel more tired.

In the evening , when the sun is about to set and the light no longer hits your retina, the melatonin is released in larger quantities. This is the signal that the night’s rest is imminent. You get more tired, relax and go to bed.

In the morning, when the first rays of light hit the bedroom, your body receives the signal that you should wake up soon. For this purpose, the release of melatonin is significantly reduced and the wake-up phase is initiated. Within about 30 minutes, the light ensures that you wake up gently and leave your tiredness behind.

The internal clock is thus largely controlled by sunlight. If it is dark, the sleep hormone will be released and if the sun slowly lights up, you will slowly wake up.


Modern everyday life will hardly allow you to align yourself with sunlight. Most of the time you have to get up earlier and especially in winter you are on your way to work or school when it is still dark outside.

But it could also be that your bedroom is facing away at sunrise . As a result, it stays dark longer and it is not possible for you to get up with the sunlight.


The light alarm clock is the solution to this problem. It has LEDs that are able to simulate a natural sunrise. If you want to be woken up at a certain time, the simulation starts about 20 to 60 minutes before you get up. Usually 30 minutes is enough to get up reliably.

At the beginning of the sunlight simulation, the daylight alarm clock glows weakly. This hardly disturbs your sleep, but ensures that the sleep hormone is hardly released any more. The light is the signal that the waking up phase begins.

Over the period of the light simulation, the lamp becomes brighter and appears whiter. At the highest level, the lamp is so bright that you are moved to get up.

If you tolerate the light, the most Lichtwecker also have an alarm . Either an alarm sound or a natural wake-up sound, such as the chirping of birds, is used here.

So you now know how a daylight alarm clock works and that it basically represents a simulation of natural sunlight. It reduces the secretion of the sleep hormone and you slide gently into the wake-up phase .


Bringing the sun into your own bedroom sounds crazy at first. But numerous testimonials from buyers underline that the daylight alarm clock fulfills its purpose. They report that getting up is easier and that the start of the day is more relaxed.

It has been confirmed that the cortisol level increases with the use of light . The cortisol in turn is essential for waking up and inhibits melatonin. You feel more awake without being exposed to the typical stress when you are suddenly torn from deep sleep.

The light also has an effect similar to that of a bright daylight lamp. It promotes the production of the happiness hormone serotonin , which gives you more energy and brightens your mood.

The wake-up light is particularly useful in winter , when the risk of seasonal depression is highest due to the dark phases . Light therapy has proven to be effective in reducing mild depressive symptoms and increasing well-being. The daylight alarm clock has a similar effect on you in the morning and thus gives you a better start to the day.

In addition, a light alarm clock can usually also be used as a reading lamp . This is useful if you want to be more awake in the evening and use the time productively. Make sure, however, that you have enough time to sleep . Otherwise you will still feel awake late at night and not be ready for sleep.


In the best case, the daylight alarm clock brings you some advantages to wake up gently and not be exposed to stress. However, various conditions must be met for this effect to be effective.


In order for the light simulation to emerge, the bedroom must be correspondingly dark. If it is too bright, the natural sunlight could outshine the daylight alarm clock. If you are so used to sleeping in the light , the sunrise simulation may no longer help you.


The alarm clock is so bright that it fills the entire room with light. This will likely cause your partner to wake up and sleep over. However, this is also the case with conventional loud alarm clocks. A real alternative are only vibration bracelets or vibrating alarm clocks that are close to the body.


The light alarm clock plays its simulation in a set period of time. This is usually 20 to 60 minutes. It is difficult to determine when you wake up. If you react sensitively, you wake up earlier. But if the light hardly has any effect on you, you will only wake up at the set wake-up time.

Due to the wake-up time it is not possible to oversleep. However, if you wake up much earlier , this could lead to a slight lack of sleep . To be on the safe side, go to sleep a little earlier in order to get a good night’s sleep in any case.


For most people, a daylight alarm clock is a significant improvement compared to a conventional alarm clock . The calm sunrise simulation lets your body wake up over a longer period of time without you suddenly being woken up from sleep.

This makes it easier to get up and is less stressful. You feel awake without needing a cup of coffee in the morning.

In addition, the light leads to the fact that the happiness hormone serotonin is released more and you are filled with energy. The mood is better and, especially in winter, depressive behaviors decrease.

The daylight alarm clock is therefore a sensible investment for every person who finds it difficult to get out of bed in the morning and is considered to be grumpy in the morning. Maybe the bad mood is just because of the wrong alarm clock?

Hello, I’m Jamie Clark, 32 years old, and I have been living in the USA for a few years.
Since I was a child, I have suffered from a house dust allergy, severely affecting me. I felt the effects both while exercising and while sleeping. Constant sneezing after getting up and difficult breathing were the consequences. The allergy has also developed into asthma, which is still a sporting restriction today.
